Epistasis refers to - The expression of one gene masking the expression of another. Which statement about a dihybrid cross is true? - It is a cross between identical double heterozygotes Which statement about mitosis is true? - Two genetically identical daughter cells are formed. Separation of the alleles of a single gene into different gametes is called - Segregation A mechanism for increasing the genetic diversity of offspring is - Sexual reproduction. In mitotic metaphase, a cell with e...

23rd pair - Sex chromosomes = determines the sex of an individual (Female: XX, Male: XY) Allele - same trait, different chromosome of homologous pair B locus - controls the color of melanin pigment: B is black; b is brown Chromosome pairs - same gene or genes affecting the same traits at corresponding positions Chromosome pairs 1-22 - carry info on how you look (eye color, hair type, height, etc). Chromosome Theory of Inheritance - 1. Genes are located on chromosomes, 2. Behavior of chromo...
